BackgroundKoshelev is the southernmost historically active volcano on the Kamchatka Peninsula. Located SW of the Pauzhetka volcano-tectonic depression and NW of Kambalny volcano, Koshelev is a complex group of four stratovolcanoes constructed along an E-W line over a Pleistocene shield volcano. Central Koshelev stratovolcano, the highest peak of the volcanic massif, is Holocene in age; north- and SE-flank craters have also been active during the Holocene. Gorely, a Holocene cinder cone related to regional basaltic monogenetic volcanicm, is located about 12 km NW of Koshelev. The largest Holocene eruption at Koshelev took place from the eastern cone about 6500 years ago. An explosive eruption was reported from Koshelev at the end of the 17th century. Major thermal fields are located in the summit crater of Valentin volcano and on the western flanks of west Koshelev volcano.
